Step-by-step solution
(1) (\mathrm{CO}_2) (s) (dry ice) [not (\left.\mathrm{CO}_2(\mathrm{~g})\right]) is used as refrigerant for ice cream and frozen food.
(2) The structure of (\mathrm{C}_{60}) contains 20 six carbon rings and 12 five carbon rings.
(3) ZSM-5 (a type of zeolite) is used to convert alcohols directly into gasoline.
(4) (\mathrm{CO}(\mathrm{g})) is colourless and adourless gas
